VPQlR-BSORBER, SMUKE AND SOOT IPREVENTER, AND HEAT-iRETAIMER.`

To ZZ whom it may concern:

Be it known that I, GEORGE l-I. BAoKMmn, a citizen of the United States,residing at Philadelphia, in the county of Philadelphia and State ofPennsylvania, have invented new and useful Improvements inVapor-Absoroers, Smoke and Scot Preventers, vand Heat-Retainers, ofwhich the following `is a specification.

My invention relates to new and useful improvements in a vapo-rabsorber, smoke and soot preventer, and heat retainer for gas stoves,and has for its object to provide an exceedingly simple and edectivedevice of this character which will be light in weight, strong anddurable and relatively inexpensive in the cost of manufacture.

A further object of the invention is to provide a device. of thischaracter which may be placed over the i'lue opening of a gas stove,although it may be used with any stove burning a liquid or gaseous fuelto prevent smoke and soot leaving the stove which ordinarily soils thewalls of the room in which the stove is located. It also prevents thevapor, thrown ofi from the burning fuel and the cooking from enteringthe atmosphere and thus keeps down obnoxious odors, and prevents theundue escape ot heat so that the oven becomes more quickly heated, andthe temperature is raised to a higher degree than the oven of a stovenot using such a device, so that the cooking may bc accomplished in ashorter length oit' timey or with aless consumption of fuel.

With these ends in view this invention consists in. the vdetails ofconstruction and combination of elements hereinafter set forth and thenspecifically designated by the claims. f

In order that those skilled in the art to which this inventionappertains may understand how to make and use the same, I will describeits construction in detail referring by numeral to the-accompanyingdrawing forming a part of this application, in which i Figure 1, is aside elevationof my improvement showingits relation to a stove. Fig. 2,a longitudinal sectional view thereof, and Fig. 3, a plan view, the capmember being removed.

In carrying out my invention as here embodied, 2 represents theextension flue or upright portion 4which is in the form of a conicalstove pipe open at both ends, the lower Spcccation of Letters Patent.

end being shaped to fit over the Harige 3 of the flue openin of thestove 4.

To the outsi e of the extension Hue 2, in proximity to its upper end issecured the flange 5 of any desired shape and size so that the upperends of said flange' and the extension ue 2 diverge toiorm a sandchamber G. To the upper end of the extenlower end and this open end isof greater diameter than the upper end of the extension flue 2, so' thata passage wav l0 is formed bef tween said cap member and the extensionflue 2. The lower edge of the cap member 9 lies in a plane below theplane of the upper edge of the extension Hue 2, or in other words their'side walls over-lap.

In thesand chamber 6, is placed a suitable filtering element such assand 1l and this is on a level with the lower edge of the cap member 9,or slightly above said lower edge in order that any vapor, grease orsmoke will not escape from the cap member 9. The bracket 7 also carriesa suitable absorbent material such kas raw cotton l2, it beingunderstood that said absorbent material is covered by the cap memberwhen the device is in use.

In practice, the device is placed upon the flue opening 3, of the stoved, and as the vaporized grease and other vapors from the burning fuel orcooking ass upward with the draft through the bo y 2, it ent-ers the capmember 9, which is farthest removed from the heat and therefore thecoolest. I prefer that this cap member be made of some material whichwill quickly condense the vapors coming in Contact with the wallsthereof. When said vapors reach this cap member they will be condensedand the odor therefrom will be absorbed bv the absorbent material 12,while the grease which condenses on the inner walls of the cap member 9,flows downward into the sand or other filtering material 11 where itwill remain, while the air escapes through the filtering material 11.

'I he parts of my device are so related to titi one another that theyvirtually form a. closure for the stove ilue and prevent the undueescape of heat so that the temperature of the oven is quickly raised and1t is found in practice that said temperature reaches a higher degreethan the temperature of the oven of the ordinary gas stove.

0f course l do not wish to be limited to the exact details ofconstruction as here shownas these may be varied within the limits ofthe appended claims without departing from the spirit of my invention.

Having thus fully described my invention, what I claim as new andusefulv is,-

1. In a device of the character described, an extension flue, meanscarried by said extension flue for holding a filtering material, a capmember over-lying the extension flue, the side walls thereof beingspaced from' the side Walls of the extension lue to form a passage wayVto the filtering material, a bracket secured to the extension ue andprojecting upwardly therefrom for supporting the cap member, and anabsorbent material carried by said bracket and inclosed by the capmember.

2. In a device of the character described, an extension ue open at' bothends, the lower end adapted to tit over the flange of a stove flue, aflange secured to said extension lue4 in proximity to its u per end,said ange projecting upwardly an diverging from the side walls of theupper end of the extension flue producing a sand chamber adapted to holda ltering material, a support carried by the upper end of the extensionflue projecting therefrom adapted to hold an absorbent material and acap member closed at its upper end, the lower end being of greaterdiameter than the upper end of the extension flue, said lower end of theextension flue member over-lapping the upper end of the extension fluethereby forming apassage way from the extension flue to the filteringmaterial.

ln testimony whereof, have hereunto affixed my signature in the presenceof two subscribing Witnesses.
